DETAILED DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to the present embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

FIG. 1 is a diagram showing a contents management system 100 according to an example embodiment of the present invention. The contents management system 100 includes a terminal 110 and a Web server 120.

The terminal 110 generates contents. According to aspects of the present invention, the contents represent data objects including at least one of audio data, video data, and text data. For example, the contents may include photographs, music, motion pictures, e-mails, electronic books, schedules, messages, and memos. However, it is understood that the types of the contents are not limited thereto.

The terminal 110 can transmit the generated contents to the Web server 120. According to an aspect of the present invention, the terminal 110 may transmit the contents to the Web server 120 automatically (such as when the contents are generated) without a user manipulation or request.

The terminal 110 may be a portable digital apparatus, such as a cellular phone, a digital camera, a PDA (Personal Digital Assistant), a notebook computer, a PMP (Portable Multimedia Player), or a MP3 player. However, it is understood that aspects of the present invention are not limited thereto. For example, the terminal 110 may also be a fixed digital apparatus, such as a digital TV, a desktop computer, or a set-top box.

The Web server 120 stores the contents transmitted from the terminal 110 and reconstructs the contents according to a predetermined criterion. The reconstruction of the contents classifies and manages the contents so that the user can easily access the contents.

The contents stored in the Web server 120 can be provided to the terminal 110 again. The Web server 120 can also provide the contents to another terminal 130, which belongs to the user (user A) or another user that has a right to access the contents. Furthermore, the user (user A) of the terminal 110 can provide the contents to a terminal 140 of another user (user B). An operation in which the Web server 120 provides the contents to a specified terminal can be performed when the corresponding terminal requests the contents or the operation. However, according to other aspects of the present invention, the operation in which the Web server 120 provides the contents to the specified terminal may be automatically performed even if the corresponding terminal does not request the contents or the operation.

Other terminals 130 and 140 can also generate contents and transmit the generated contents to the Web server 120. That is, the terminal 130 and the terminal 140 can perform the same operation that is performed by the terminal 110. However, for convenience of explanation, in the embodiment, it is assumed that the terminal 110 generates the contents and transmits the generated contents to the Web server 120. Hereinafter, the operations performed by the terminal 110 and the Web server 120 according to aspects of the present invention will be described.

A communication method that is used by the terminal 110 to access the Web server 120 varies according to a communication environment of the terminal 110 and/or the Web server 120. An example is shown in FIG. 2.

FIG. 2 is a diagram showing a communication environment of a terminal 110 according to an example embodiment of the present invention. In this embodiment, it is assumed that the terminal 110 is connected to the Internet 210 via a network, such as a WiFi network 220, a CDMA network 230, and a WiBro network 240, so as to access the Web server 120.

When the terminal 110 is located at an office or at home, for example, the terminal 110 can connect to the Internet 210 on the basis of WiFi (Wireless Fidelity) network 220. If the terminal 110 is out of a communication range of an access point (AP) 220 at the office or at home, the terminal 110 can be connected to Internet 210 on the basis, for example, of a CDMA (Code Division Multiple Access) network 230. Further, when the terminal 110 is moving at high speed, the terminal 110 can be connected to Internet 210 using, for example, a WiBro (Wireless Broadband Internet) network 240. Specifically, network service providers 224, 234, and 244 that support the connection of individual communication networks 220, 230, and 240 to the Internet 210 can exist, and the terminal 110 can access the Web server 120 through the network service providers 224, 234, and 244.

According to the location of the terminal 110, the terminal 110 may use a plurality of communication methods to access the Web server 120. For example, the terminal 110 can connect to the Internet 210 at home on the basis of both WiFi and CDMA. Accordingly, if a plurality of communication methods can be used to access the Web server 120, the terminal 110 can select one or more communication methods from the plurality of communication methods. The accessing of the Web server 120 by the terminal 110 will now be described with reference to FIG. 3.

FIG. 3 is a flowchart showing a method in which a terminal 110 accesses a Web server 120 according to an embodiment of the present invention. Referring to FIGS. 2 and 3, when access to the Web server 120 is needed (for example, when the user requests the access or the contents are to be transmitted to the Web server 120, the terminal 110 searches for a currently-usable communication method in operation S310. For example, if an access point 222 that supports WiFi exists in the vicinity of the terminal 110, the terminal 110 receives a beacon cyclically transmitted from the access point (AP) 222 to thereby recognize that WiFi communication is usable. Alternatively, if a base station 232 that supports CDMA communication exists in the vicinity of the terminal 110, the terminal 110 receives a base station signal cyclically transmitted from the base station 232 to thereby recognize that CDMA communication is usable. Similarly, if a base station 242 that supports WiBro communication exists in the vicinity of the terminal 110, the terminal 110 receives a base station signal cyclically transmitted from the base station 242 to thereby recognize that WiBro communication is usable. It is understood that other communication methods may be searched or used.

Next, the terminal 110 determines whether the usable communication method exists in operation S320. If the usable communication method does not exist (operation S320), the terminal 110 informs the user that access to the Web server 120 cannot be performed in operation S330.

Meanwhile, if the usable communication method exists (operation S320), the terminal 110 determines whether a plurality of communication methods exist in operation S340. If a plurality of usable communication methods exist (operation S340), the terminal 110 selects one communication method from the plurality of communication methods according to a prescribed criterion (hereinafter, referred to as a “communication method selection criterion”) in operation S350.

A billing policy of the communication method is an example of the communication method selection criterion. In this case, the terminal 110 can use a communication method having the lowest charge rate from the plurality of communication methods. For example, if Internet communication based on WiFi is charged according to a flat rate and Internet communication based on the CDMA is charged according to an hourly rate, in a communication environment where both the WiFi and CDMA are usable, the WiFi that does not require an additional fee is selected according to the communication method selection criterion. It is understood that, according to other aspects, the terminal 110 does not necessarily compare and analyze the fees of the individual communication methods. For example, if a priority is set in advance for the individual communication methods on the basis of respective communication fees, manually, or other characteristics (such as signal strength), the terminal 110 can select a communication method to be used according to the set priority. Here, the priority can be set by the user or a manufacturer of the terminal.

A communication condition is another example of the communication method selection criterion. In this case, the terminal 110 can select a communication method having a lowest traffic from the plurality of usable communication methods or a communication method having a strongest connection intensity to a repeater (for example, the intensity of a signal to be cyclically transmitted from the repeater). Moreover, is it understood that other communication method selection criterions may be used.

Once the communication method is selected (operation S350), the terminal 110 accesses the Web server 120 using the selected communication method in operation S360. Meanwhile, if a single usable communication method exists (operation S340), the terminal 110 can access the Web server 120 using the corresponding communication method in operation S360.

When accessing the Web server 120, the terminal 110 may, although not necessarily, transmit predetermined authentication information to the Web server 120. The authentication information is information to authenticate the user of the terminal 110 and may include, for example, a user ID and a password. It is understood that other or additional information may be used to authenticate the user, such as an identifier of the terminal 110 (for example, an MAC address of the terminal 110). The Web server 120 identifies and authenticates the user of the terminal 110 through the authentication information transmitted from the terminal 110. To this end, the user may register the authentication information in the Web server 120 in advance. The registration of the authentication information can be performed in a similar manner to a subscription process to a Web site. However, it is understood that aspects of the present invention are not limited thereto.

When the terminal 110 can communicate with or access the Web server 120, the terminal 110 can transmit the generated contents to the Web server 120. The transmitting of the generated contents will now be described with reference to FIGS. 4 and 5.

FIG. 4 is a flowchart showing a method in which a terminal 110 transmits contents to a Web server 120 according to an embodiment of the present invention. FIG. 5 is a flowchart showing a method in which a terminal 110 transmits contents to a Web server 120 according to another embodiment of the present invention

Referring to FIGS. 2 and 4, the terminal 110 generates contents in operation S410. For example, when the terminal 110 includes an imaging element, the terminal 110 can generate photographs or motion pictures. Similarly, when the terminal 110 includes a short message editor, the terminal 110 can generate short messages. In addition, the terminal 110 that has a scheduling application (hereinafter, referred to as “scheduler”) can generate a schedule of a user according to the user's input. Moreover, it is understood that the terminal 110 can generate other types of contents according to functions provided therein.

As such, the terminal 110 directly creates the contents using the functions provided therein to generate the contents. However, aspects of the present invention are not limited thereto. For example, according to other aspects of the present invention, the terminal 110 may generate the contents by receiving the contents from another apparatus or network and/or modifying the received contents, thereby creating new contents. Furthermore, according to another example, the terminal 110 may connect to a portable storage device (such as a multimedia card, an SD card, or a memory stick) and acquire contents stored in the portable storage device, wherein the acquired contents can be handled as the contents generated by the terminal 110. Alternatively, the terminal 110 can receive a short message from another terminal, and the received short message can be handled as the contents generated by the terminal 110.

After generating the contents (operation S410), the terminal 110 transmits the generated contents to the Web server 120 in operation S420.

According to the embodiment shown in FIG. 4, whenever new contents are generated, the terminal 110 transmits the generated contents to the Web server 120. That is, the generated contents are transmitted from the terminal 110 to the Web server 120 in real time. However, aspects of the present invention are not limited thereto. For example, when a predetermined condition is satisfied, the terminal 110 may transmit all the generated contents to the Web server 120 at one time. An example is shown in FIG. 5.

Referring to FIG. 5, although a method in which the terminal 110 generates the contents is omitted, it is understood that the terminal 110 generates the contents (as described above with reference to operation S410 in FIG. 4) and stores the generated contents. As a separate operation from the generation and storage of the contents, the terminal 110 determines whether a contents transmission condition is satisfied in operation S510. The contents transmission condition may be a default condition or may be set or changed by the user.

Information about whether it is a time to transmit the new contents generated by the terminal 110 to the Web server 120 is an example of the contents transmission condition. Specifically, if a time period from midnight to 3 a.m. is set for the contents transmission condition, the terminal 110 compares a current time with the time set for the contents transmission condition and then determines whether the contents transmission condition is satisfied.

A communication method that is to be used by the terminal 110 is another example of the contents transmission condition. In detail, when the terminal 110 is a portable digital apparatus, the position of the terminal 110 frequently changes. As the position of the terminal 110 changes, a communication method that is used by the terminal 110 to access the Web server 120 may also change (as described above with reference to FIG. 2). Accordingly, if a specified communication method is set for the contents transmission condition, whenever the communication method is changed, the terminal 110 compares the changed communication method with the communication method set for the contents transmission condition and then determines whether the contents transmission condition is satisfied.

It is understood that aspects of the present invention are not limited to the above-described examples of the contents transmission condition, and other contents transmission conditions may be used.

If the contents transmission condition is satisfied (operation S510), the terminal 110 determines whether newly generated contents exist in operation S520. Here, the newly generated contents are contents stored in the terminal 110 that have not already been transmitted to the Web server 120.

If the newly generated contents exist (operation S520), the terminal 110 transmits the corresponding contents to the Web server 120 in operation S530. For the contents transmission, the terminal 110 accesses the Web server 120 as described above, for example, with reference to FIG. 3. The Web server 120 reconstructs the contents transmitted from the terminal 110. The reconstructing of the contents will now be described with reference to FIG. 6.

FIG. 6 is a flowchart showing a content management method of a Web server 120 according to an embodiment of the present invention. Referring to FIGS. 2 and 6, the Web server 120 receives contents from the terminal 110 in operation S610. Then, the Web server 120 reconstructs the received contents according to attributes of the contents in operation S620. Here, the attributes are, for example, information explaining the contents or identifying categories relating to the contents. Examples of the attributes include the types of the contents (for example, music, motion picture, photograph, e-mail, memo, short message, or schedule), meta data in the contents, and contexts of the contents.

The meta data can be divided into common information common to all the contents and individual information specific to each of the contents. Examples of the common information include a contents generation position, a contents generation time, and a character related to the contents. Examples of the individual information include a genre, an artist, and an album where the contents are music, and a keyword, a writer, and a genre where the contents are electronic books. It is understood that other types of common information and individual information can exist.

The meta data can be added to the contents on the basis of information input by the user of the terminal 110. However, aspects of the present invention are not limited thereto. Alternatively, the meta data may be automatically added to the contents according to functions provided by the terminal 110. For example, the terminal 110 that can confirm the position using information regarding the GPS or base station can automatically add, to the contents, positional information when the contents are generated. Furthermore, the terminal 110 that cyclically receives current time information from the base station or a timer function can add time information at which the contents are generated to the contents as the meta data.

Meanwhile, in order to reconstruct the contents according to the contexts of the contents, the Web server 120 can include a function of analyzing the contents. A technical method of analyzing the contexts may vary according to the types of the contents. For example, when the contents are short messages or schedules, the Web server 120 extracts words from the short messages or the schedules, compares the extracted words with previously recorded words, and subsequently lists the contents in an appropriate category. If the contents are photographs, the Web server 120 extracts a face image from the photograph, analyzes a feature of the extracted face image, and subsequently determines whether a previously registered character exists in the photograph. If the previously registered character exists in the photograph, the Web server 120 can list the photograph in a category related to the corresponding character.

It is understood that aspects of the present invention are not limited to the above-described contents reconstruction methods. The contents reconstruction method may vary according to services that are provided by the Web server 120. Furthermore, the kinds of the attributes as the criterion of the contents reconstruction may also vary according to the embodiments.

The Web server 120 stores the reconstructed contents, and updates the contents list stored therein according to the reconstructed contents in operation S630.

Though not shown in FIG. 6, it is understood that the contents reconstruction or contents list update operation can be performed according to the user. That is, according to the authentication information or identification information transmitted from the terminal 110, the Web server 120 can update a contents list corresponding to the user, or store contents corresponding to the user transmitting the contents received in operation S610.

The contents reconstructed by the Web server 120 can be provided to the terminals 110, 130, and 140 (illustrated in FIG. 1) that require the contents. The transmitting of the contents from the Web server 120 to the terminals 110, 130, and 140 will now be described with reference to FIGS. 7 to 10.

FIG. 7 is a diagram showing a method in which a terminal 110 receives contents from a Web server 120 according to an embodiment of the present invention. Referring to FIG. 7, the terminal 110 first requests contents search information from the Web server 120 in operation S710. To request the contents search information (operation S710), the terminal 110 accesses the Web server 120 as described above, for example, with reference to FIG. 3. The contents search information is information used to construct a user interface for guiding the search of the contents, and can include the contents list updated in operation S630 of FIG. 6.

Upon receiving the request from the terminal 110, the Web server 120 transmits the contents search information stored therein to the terminal 110 in operation S720. The terminal 110 displays the contents search information transmitted from the Web server 120 in operation S730.

The contents search information can be provided in a variety of ways according to a contents reconstruction criterion or reconstruction result. For example, the contents search information can include the contents list, arranged on the basis of at least one attribute. The contents search information shown in FIG. 8A is provided such that the contents are searched for on the basis of time and position attributes. That is, the user can search the contents according to the contents generation time and position using the contents search information.

In the contents search information, the search criterion can be modified (for example, an attribute can be added or changed). For example, referring to FIG. 8A, if a request to add a character attribute is input from the user, the terminal 110 can transmit a request to the Web server 120 to add the character attribute. According to the request of the terminal 110, the Web server 120 can transmit the contents search information including the character attribute to the terminal 110. Then, as shown in FIG. 8B, the terminal 110 can display the contents search information including the character attribute. However, it is understood that according to other aspects of the present invention, the terminal 110 does not need to request the Web server 120 to add or change the attribute as the search criterion, and the contents search information transmitted from the Web server 120 in operation S720 may be constructed such that the attribute as the search criterion can be changed or added solely within the terminal 110.

FIG. 9 is a diagram showing contents search information according to another embodiment of the present invention. In the contents search information shown in FIG. 9, the attribute of the contents is represented by a text. The size of the text represents an importance of each attribute. For example, the larger that the size of the text is, the more the number of contents related to the corresponding attribute is. It is understood that aspects of the present invention are not limited to a size representation of the importance of each attribute. For example, the importance of each attribute may be represented by the color of the text. Furthermore, instead of or in addition to the text, an icon may be used.

The structures of the contents search information shown in FIGS. 8A through 9 are just examples of the present invention, and are not intended to limit aspects of the present invention. The user can search and select desired contents through the contents search information to be displayed on the terminal 110.

Returning to FIG. 7, if the user selects specified contents from the displayed contents search information, the terminal 110 requests the selected contents from the Web server 120 in operation S740. The Web server 120 transmits the requested contents to the terminal 110 in operation S750. The Web server 120 may transmit the requested contents in operation S750 according to a download method or a streaming method, depending for example on the type of the contents or setting.

Although FIG. 7 shows the operation between the terminal 110 that transmitted the contents to the Web server 120 (as shown in FIGS. 4 and 5) and the Web server 120, the same operation can be performed between another terminal 130 (illustrated in FIG. 1) of the same user or the terminal 140 (illustrated in FIG. 1) of another user and the Web server 120. For example, the user of the terminal 110 can register authentication information of another user in the Web server 120 in advance such that the contents transmitted from the terminal 110 to the Web server 120 and managed by the Web server 120 can be provided to the terminal 130 of another user.

FIG. 10 is a diagram showing a method in which a terminal 110 receives contents from a Web server 120 according to an embodiment of the present invention. Referring to FIG. 10, the terminal 110 transmits a search condition to the Web server 120 in operation S1010. The search condition can include one or more keywords for defining the attribute of the contents. According to an aspect of the present invention, the search condition can be transmitted to the Web server 120 together with the request to transmit the contents.

The Web server 120 searches contents corresponding to the transmitted search condition transmitted in operation S1020. For example, if a search condition including a keyword “company” is transmitted, the Web server 120 can search contents related to a company. Since the contents stored in the Web server 120 are classified according to the attributes, the contents corresponding to the search condition can be easily searched even though there are a large number of contents to be managed by the Web server 120. Here, among the contents stored in the Web server 120, the contents of the user that uses the terminal 110 or the contents of other users who belong to the same community as the user of the terminal 110 may be included within a search range.

If the contents corresponding to the search condition are found (operation S1020), the Web server 120 transmits the found contents to the terminal 110 in operation S1030.

Although FIG. 10 shows a case where the Web server 120 immediately transmits the contents found by the search operation to the terminal 110, aspects of the present invention are not limited thereto. The Web server 120 may transmit a list of the contents found in operation S1020 to the terminal 110. In this case, the terminal 110 can display the contents list. If the user selects specific contents from the contents list, the terminal 110 can request the selected contents from the Web server 120. Thereafter, the Web server 120 can transmit the contents requested by the terminal 110 to the terminal 110.

According to an aspect of the present invention, the Web server 120 can automatically transmit the contents transmitted from the terminal 110 to another terminal 130 of the user that uses the terminal 110. For example, the Web server 120 can transmit e-mails, schedules, and memos to a PDA, transmit music to an MP3 player, and transmit photographs and motion pictures to a PMP or a digital TV.

Furthermore, the user can set contents to be transmitted and a terminal to which the contents are transmitted. Accordingly, the user can register, in the Web server 120, an identifier (for example, a MAC address) of the terminal 130 and the types of the contents to be transmitted to the terminal 130. The Web server 120 can transmit the contents to the corresponding terminal 130 with reference to the information.

In order to allow the Web server 120 to automatically transmit the contents to the terminal 130 even though the terminal 130 does not request the contents, the terminal 130 must be connected to a network, such as the Internet, though which the terminal 130 can connect to the Web server 120. When the terminal 130 is a fixed digital apparatus (such as a digital TV, a set-top box, or a desktop computer), the terminal 130 can constantly be connected to the network. Meanwhile, when the terminal 130 is a portable digital apparatus (such as an MP3 player, a cellular phone, a PDA, and a PMP), the terminal 130 can be irregularly connected to the network.

If the terminal 130 is connected to the network, the Web server 120 can immediately transmit the contents received from the terminal 110 to the terminal 130. Meanwhile, if the terminal 130 is not connected to the network, the Web server 120 can transmit the contents to the terminal 130 once the terminal 130 connects to the network. Then, when the terminal 130 is connected to the network, the Web server 120 can transmit the contents received from the terminal 110 to the terminal 130.

In order to allow the Web server 120 to automatically transmit the contents to the terminal 130, the address of the terminal 130 on the network (for example, an IP address) is needed. To this end, when connected to the network, the terminal 130 can transmit, to the Web server 120, information that the terminal 130 is connected to the network. This information can include a network address allocated to the terminal 130 (for example, an IP address). Accordingly, the Web server 120 can automatically transmit the required contents to the terminal 130.

FIG. 11 is a block diagram showing a configuration of a terminal 110 illustrated in FIG. 1 according to an embodiment of the present invention. It is understood that other terminals 130 and 140 illustrated in FIG. 1 can have the same configuration as that of the terminal 110.

The user input unit 1160 receives user inputs. That is, the user can request to execute the contents, request to generate the contents, or request the Web server 120 to search the contents through the user input unit 1160, although not limited thereto. To this end, the user input unit 1160 can manipulation devices, including buttons, a touch pad, a touch screen, or a jog switch.

The control unit 1170 performs the operations to select a communication method to be used by the communication unit 1110 (operations S310, S320, S340, and S350 illustrated in FIG. 3) or the operations to determine whether to transmit the contents to the Web server 120 through the communication unit 1110 (operations S510 and S520 in FIG. 5). Furthermore, the control unit 1170 can generate a request message to request the contents search information from the Web server 120 or to transmit the contents search condition. In addition, the control unit 1170 can control the operations of the individual components of the terminal 110 so that the terminal 110 can appropriately perform the required operations, as described above with reference to FIGS. 1 through 10.

FIG. 12 is a block diagram showing a configuration of a Web server 120 according to an embodiment of the present invention. The Web server 120 includes a network connection unit 1210, an authentication unit 1220, a contents reconstruction unit 1230, a storage unit 1240, a contents list management unit 1250, and a control unit 1260.

The network connection unit 1210 receives contents, data, and information from the terminal 110, and transmits contents, data, and information to the terminal 110. It is understood that the network connection unit 1210 does not necessarily directly communicate with the terminal 110. As described above with reference to FIG. 2, the network connection unit 1210 can communicate with the terminal 110 through network service providers 224, 234, and 244.

The authentication unit 1220 identifies and authenticates the user of the terminal 110 using authentication information (for example, the user ID and password or the MAC address of the terminal 110) transmitted from the terminal 110. Further, the authentication unit 1220 may manage authentication information of other users belonging to the same community as the user of the terminal 110, together with the authentication information of the user of the terminal 110. Furthermore, the authentication unit 1220 can manage identification information of another terminal 130 of the user who uses the terminal 110 and the types of the contents to be automatically transmitted to the other terminal 130.

The contents reconstruction unit 1230 reconstructs the contents received from the terminal 110. For example, when the contents are music files, the contents reconstruction unit 1230 can classify the music files on the basis of the genre, the artist, and the album with reference to meta data in the music file. When the contents are electronic books, the contents reconstruction unit 1230 can classify the electronic books according to the keyword, the writer, and the genre by referring to meta data in the electronic books or by analyzing the context of the electronic books. When the contents are schedule files, the contents reconstruction unit 1230 can classify the schedule files according to title, date, and content. When the contents are e-mails, the contents reconstruction unit 1230 can classify the e-mail according to transmission time, title, importance, and attachments. These contents reconstruction methods are just examples of the present invention, and are not intended to limit aspects of the present invention. Accordingly, the contents reconstruction unit 1230 can analyze various attributes of the contents and reconstruct (or reorganize) the contents according to the attributes of the contents, as described above, for example, with reference to FIG. 6.

The storage unit 1240 stores the contents received from the terminal 110. The storage unit 1240 may store the contents in a storage area that is allocated to a user authenticated by the authentication unit 1220 (a user of a terminal from which the contents are transmitted). The storage area may be logically or physically separated from storage areas allocated to other users.

The contents list management unit 1250 manages a contents list including information regarding the contents stored in the storage unit 1240. If the storage unit 1240 stores new contents, the contents list management unit 1250 updates the contents list to include information regarding the newly stored contents. The information regarding the contents in the contents list can be acquired from the contents reconstruction unit 1230. It is understood that the contents list managed by the contents list management unit 1250 may be divided such that there exists a plurality of contents lists, each corresponding to a user. Furthermore, the contents list management unit 1250 can manage the contents search information that is used to provide a user interface in the terminal 110 to search the contents. The contents search information includes the contents list. When transmitted to the terminal 110, the contents search information can be displayed as a user interface.

The control unit 1260 searches the contents stored in the storage unit 1240 and analyzes request messages transmitted by the terminal 110. Moreover, the control unit 1260 can identify a terminal to which the contents or the contents search information are transmitted through information managed by the authentication unit 1220. In addition, the control unit 1260 can control the operations of the individual components of the Web server 120 such that the Web server 120 can appropriately perform the required operations described above with reference to FIGS. 1 through 10.
